Technically the atomic composite probably has more aluminum than the raw does!
I have no signal issues with the fusion. Check my video. Reception is probs like this:
1.Atomic composite (not all aluminium)
2.Fusionwerkz Raw
3.Vapor
4.Atomic
5.Alumacase
If you want an all aluminium case and want the best signal then the Raw is the way to go! The atomic is just a plastic case with a bit of aluminium and is not an aluminium case in my book.
Good night.
